The improvement of technology applied to the automotive sector is unquestionable. But depending on how you look at it, there are brands in which they have worked more and better and others that still have a way to go. Peugeot is one of the ones that has evolved the most and we have proof of its work in the i-Cockpit that almost all its models mount. In others we also see progress, but in all of them there is a "quasi" erotic "dream: a screen that cleans itself No?
Yes, because in recent years we have attended the exponential growth of screens. And the worst of all is not that, it is that they are a constant source of distractions for both the driver and the passengers. In addition, the inconveniences that they entail go further, such as the trace of dirt and marked fingers that always go on the surface. But General Motors wants to end everything by patenting a screen that cleans itself Will it be a dream?
The screen that cleans itself is a General Motors patent that could be a reality in the future...
As you well know, the size of the screens of General Motors cars has grown. That is a fact even if the models of the Yankee group arrive in Europe with a dropper. Well, to prevent the owners of their cars from complaining "bitterly" about the dirt accumulated on the monitors, they have come up with this new solution. As stated in the US Patent and Trademark Office registration It is a "miracle"...
Although more than a miracle it is the practical application of a photocatalytic system activated by ultraviolet LEDs that are integrated into the RGB matrix of the screen itself. And you wonder when reading all this if it's a tall tale or not. Well, the key to this system is in the violet color that incorporates these screens and would be added to the Red, Green and Blue colors that are already used. The change would be that the wavelength is shorter.
Thus UV waves are invisible to the human eye. making it take charge of executing the photocatalysis process. To do this, General Motors indicates that on its screens there will be a transparent layer that includes a photocatalyst reactive to this ultraviolet light. In this way, the integrated photocatalyst should react with certain wavelengths of light to produce a chemical reaction and remove dirt like this.
All in all, this is the quick and easy way to explain how it works, but the system has more substance. And not only that, As GM explains, these new screens would not change their design with respect to which we already know. In the event of a reconsideration, this will be minimal and negligible, so customers will not notice. What matters most to us here is that the system works and the dream that the screen cleans itself stops being such... No?
